Absorption Refrigeration

Abstract

This section is not a design manual for absorption plant; it is included because of the growing use of the method, particularly for chilling either for cool storage or for air-conditioning. Although not as efficient as vapour cycle methods when considered in crude energy terms, the absorption method uses much less mechanical work which, of course, has involved losses in its original production at the power plant. It does use more energy but this energy can be at a relatively low level of temperature, e.g. what might otherwise be waste heat, or be attainable from relatively simple solar collectors.
